Focusing on the shortage of multidisciplinary data management systems of current integrated design environment, a dynamic integration and scheduling strategies of data was built, using a unified multidisciplinary semantic-oriented data management method on the basis of the analysis of characteristics of data in launch vehicle design process. The application in an integrated design environment of a solid rocket vehicle proves that the multidisciplinary semantic-oriented method separates data dealing from processing dealing, and simplifies the data description and access. Consequently, the flexibility, expansibility and versatility of vehicle integration design environment are enhanced.
